Spectral Transmission and Attenuation of X-Radiation by Glasses and Resins Used in Color Television Picture Tubes

Any device capable of accelerating electrons to an energy of several thousand electrons volts can be a source of X-radiation. Color television receivers have been shown to produce amounts of X-rays in excess of the recommendations of the National Council on Radiation Protection and Measurements (NCRP), under certain conditions of construction and operation (Refs. 2,3,4,5,6,7). The X-rays may be produced by shunt regulator, high voltage rectifier and picture tubes, and the penetrability of the emissions is sufficient to create hazardous conditions for the lens of the eye, thyroid, male gonads, and some bone marrow (Refs. 2,8,9,10,11). This study was conducted to determine the variables affecting the X-ray protective properties of selected glasses and bonding resins used in the manufacture of color television picture tubes.
